Measurement of Poroelastic Pressure Response

1. A method for characterizing a subterranean formation during a hydraulic fracturing operation comprising: injecting a fluid into an active well of the subterranean formation at a pressure sufficient to induce one or more hydraulic fractures; measuring, via a pressure sensor, a poroelastic pressure response caused by the inducing of the one or more hydraulic fractures, wherein the pressure sensor is in at least partial hydraulic isolation with the one or more hydraulic fractures, extracting at least one characteristic of a poroelastic pressure response to create a pressure signature, comparing the pressure signature to a library of pressure signatures, and estimating at least one physical characteristic of the induced hydraulic fractures based on the library of pressure signatures wherein said characteristic of poroelastic pressure response is selected from one or more of an elapsed time to reach maximum pressure (Δt max ), elapsed time to reach minimum pressure (Δt min ), maximum deviation in poroelastic pressure (Δp max ), minimum deviation in poroelastic pressure (Δp min ), and maximum slope (max Δp/Δt).

2. The method of claim 1 , wherein the hydraulic fracturing operation is a multi-zone hydraulic fracturing operation.

3. The method of claim 1 , wherein the pressure sensor is installed at the surface or in the active well.

4. The method of claim 3 , wherein the active well is divided into multiple zones by a well plug.

5. The method of claim 4 , wherein at least one of the multiple zones is hydraulically isolated.

6. The method of claim 4 , wherein the pressure sensor is installed inside a zone of the multi-zone zones.

7. The method of claim 1 , wherein the pressure sensor is installed outside of a casing in the active well.

8. The method of claim 1 , wherein the poroelastic pressure response is measured through an open toe of the active well.

9. The method of claim 1 , wherein the pressure sensor is a pressure gauge.

10. The method of claim 1 , wherein the pressure sensor is conveyed through casing or tubing, suspended at wellhead, or installed permanently or temporarily.

11. A method for producing hydrocarbons comprising: injecting a fluid into the subterranean formation to induce one or more hydraulic fractures; and measuring a poroelastic pressure response, via a pressure sensor, through a monitor well, wherein the poroelastic pressure response is caused by inducing of the one or more hydraulic fractures, extracting at least one characteristic of a poroelastic pressure response to create a pressure signature wherein said characteristic of poroelastic pressure response is selected from one or more of an elapsed time to reach maximum pressure (Δt max ), elapsed time to reach minimum pressure (Δt min ), maximum deviation in poroelastic pressure (Δp max ), minimum deviation in poroelastic pressure (Δp min ), and maximum slope (max Δp/Δt), comparing the pressure signature to a library of pressure signatures, changing one or more parameters of a fracturing design during fracturing, and producing hydrocarbons from said subterranean formation.

12. The method of claim 11 , wherein the hydraulic fracturing operation is a multi-zone hydraulic fracturing operation.

13. The method of claim 11 , wherein the pressure sensor is installed at the surface or in the monitor well.

14. The method of claim 11 , wherein the monitor well is divided into multiple zones.

15. The method of claim 14 , wherein at least one of the multiple zones is hydraulically isolated.

16. The method of claim 14 , wherein the pressure sensor is installed inside a zone of the multi-zone zones.

17. The method of claim 11 , wherein the pressure sensor is installed outside of a casing in the monitor well.

18. The method of claim 11 , wherein the poroelastic pressure response is measured through an open toe of the monitor well.

19. The method of claim 11 , wherein the pressure sensor is a pressure gauge.

20. The method of claim 11 , wherein the pressure sensor is conveyed through casing or tubing, suspended at wellhead, or installed permanently or temporarily.
